The Siemens 3VA2340-6KP32-0JC0 is a SENTRON molded case circuit breaker rated for 400 A continuous current Iu at 40 °C through 50 °C ambient, with a 3-pole configuration and an ETU850 electronic trip unit for line protection. At 55 °C it derates to 375 A, at 60 °C to 350 A, at 65 °C to 325 A, and at 70 °C to 300 A — so if your panel runs hot, the actual ampacity drops. Breaking capacity is 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V, which covers most industrial distribution fault levels without cascading upstream.
